“…Dual polarized dipole (see [26][27][28][29][30][31]) and horn antennas (see [32][33][34][35]) can already be found in the literature. Most of these antennas have the disadvantage that they have crossed feed points.…”

“…In general, UWB antennas can be classified into two types, omni-directional antennas and unidirectional antennas, according to their radiation patterns. These antennas can be utilized for impulse radiation or work as multi-band antennas [2]. The radiation patterns of them is mainly the conical radiation patterns [3], [4], so they can not satisfy some significant demands in many applications.…”

A simple ultra-wideband magneto-electric dipole antenna utilizing a differential-fed structure is designed. The antenna mainly comprises three parts, including a novel circular horned reflector, two vertical semicircular shorted patches as a magnetic dipole, and a horizontal U-shaped semicircular electric dipole. A differential feeding structure working as a perfect balun excites the designed antenna. The results of simulation have a good match with the ones of measurement. Results indicate that the designed antenna achieves a wide frequency bandwidth of 107 % which is 3.19~10.61 GHz, when VSWR is below 2. Via introducing the circular horned reflector, the designed antenna attains a steady and high gain of 12 ± 1.5dBi. Moreover, settled broadside direction main beam, high front-to-back ratio, low cross polarization, and the symmetrical and relatively stable radiation patterns in the E-and H-plane are gotten in the impedance bandwidth range. In the practical applications, the proposed antenna that is dc grounded and has a simple structure satisfies the requirement of many outdoor antennas.

“…With the rapid development of modern wireless system, wideband antennas are more extensively applied than ever. 11,12 However, one major drawback of the DRA is the narrow bandwidth, which is not sufficient for many wideband applications. 13 Recently, great efforts have been paid on the frequency tunable DRA and various frequency tuning techniques have been exploited.…”

Absorption enhancement and total absorption in a graphene-waveguide hybrid structure AIP Advances 7, 025101 (2017); https://doi.org/10.1063/1.4975706The influence of the edge effect on the skyrmion generation in a magnetic nanotrack AIP Advances 7, 025105 (2017) A thermally tunable slot-coupled dielectric resonator antenna (DRA) has been designed and prepared by placing a thermosensitive ceramic resonator onto the slot. Typical magnetic resonance occurs in the resonator, which is closely related to its dielectric constant. Because the dielectric constant of the ceramic resonator decreases as the temperature increases, the resonance frequency of the proposed DRA increases as the temperature increases. The simulated results are in good agreement with the measured ones, which confirms the thermally tunable behavior. This approach provides a way for designing the frequency tunable antennas. © 2017 Author(s).
